Yundu's name means "light green" in Korean. Or "chartreuse." He spends his days in a design store in a repurposed building turned into galleries and a shop and cafe called BoAn. A sign tells you not to touch Yundu. And not call his name. He will trot into the room with great purpose then quickly turn around and trot out as if the urgent business was elsewhere. Yundu will not make eye contact and might seem aloof. Eventually Yundu will lay out by the big window and watch the world go by. And then you'll feel like you two have something in common.
